Reduced-complexity Adaptive Loop Filtering via Input-dependent Graph Filters
Wen-Yang Lu, Eduardo Pavez, Antonio Ortega +2
Adaptive Loop Filtering is an important tool for suppressing compression artifacts in modern video codecs. In the enhanced compression model (ECM), a software test model used for e…

INT-DTT+: Low-Complexity Data-Dependent Transforms for Video Coding
Samuel Fernández-Menduiña, Eduardo Pavez, Antonio Ortega +4
Discrete trigonometric transforms (DTTs), such as the DCT-2 and the DST-7, are widely used in video codecs for their balance between coding performance and computational efficiency…

Adaptive Online Learning of Separable Path Graph Transforms for Intra-prediction
Wen-Yang Lu, Eduardo Pavez, Antonio Ortega +2
Current video coding standards, including H.264/AVC, HEVC, and VVC, employ discrete cosine transform (DCT), discrete sine transform (DST), and secondary to Karhunen-Loeve transform…
